WALTER F. SMITH, OF GREEN POINT, NEW YORK.

IMPROVED SAD- IRON HEATER.

Specification forming part of Letters Patent No. 44,350, dated September 20, 1864.

To all whom it may GUM/06in.

Be it known that I, WALTER F. SMITH, of Green Point, in the county of Kings and State of New York, have invented a new and Improved Sad-Iron Heater; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which-' Figure 1 represents a longitudinal vertical section of my invention, taken in the plane indicated by the line :0 a, Fig. 2. Fig. 2 is a plan or top view of the same, some parts being broken away to expose the interior of the heater.

Similar letters of reference indicate like parts.

This invention consists of a furnace made in the form of a sadiron, and provided with an angular grate, and with a top which is perforated with two holes, one to expose the sole of the sad-iron placed thereon to the direct influence of the heat emanating from the fire in the furnace, and the other to carry off the products of combustion in such a manner that by the angular shape of the grate the heat from the fire is equally diffused over the entire sole of the sad-iron, and the rear portion of tne same is heated equally fast as its point, and that by the use of my heater the operation of heating sad-irons can be effected with'littlc fuel and without a stove or furnace which will emit much heat.

A represents a hollow box or furnace cast of iron or made of any other suitable material in the form of a huge sad-iron, and pro- \ided with three (more or less) legs, B.

U is the fire-grate, which is suppoited by a rim, (0, in the lower part of the furnace, and t) which air is admitted through the drafthole D. Said grate, instead of being flat, as grates of the ordinary construction, is bent or curved up, as clearly shown in Fig. 1 of the drawings, and the draft-hole extends up close under the highest part of the grate. The inclined or curved portion of the grate occupies about two-fifths of its whole length, and the air in passing through the draft-hole strikes said inclined or curved part, as indicated by the arrows in Fig. 1, and the heat is thrown up against the rear portion of the sad-iron and equally difiused over the entire sole of the same, whereas if the grate is flat tle products of combustion tend to rise in an inclined direction toward the flue which is intended to carry the same off, and the point of the sad-iron is heated much quicker than its rear.

The sad-iron is placed on the top-plate E of the furnace, which is supported by a rim, b, and this top plate is peiforated with two holes, 0 d, one to admit the heat directly to the sole of the sad-iron and the other to carry oft the products of combustion. The hole 0 is made in the shape of the bottom of a sadiron, but somewhat smaller, and it extends to within half or three-quarters of an inch to the hole (I, which is surrounded by a flange, to re ceive a chimney, which will increase the draft of the fire. A plate, 6, fitting on the hole 0, serves to cover the same up when the heater is not to be used.

This heater is very simple in its construe tion, it can be made entirely out of cast-iron, it requires no fitting, and it is of great advantage not only for tailors, batters, and other trades where sad-irons have to be used very frequently, but it can also be used with advantage in every family and laundry to heat the irons in summer time, particularly in order to avoid the heat emanating from a large stove and to save the fuel necessary to heat the same.

What I claim as new, and desire to secure by Letters Patent, is-

l. Asad-iron heater constructed as herein described as a new article of manufacture.

2. The augularfire-grate G, in combination with the draft-hole l) and top-plate E, with holes 0 d, constructed and operating in the manner and for the purpose substantially as shown and described.
